'6 Claims.

The present invention relates to a new and improved building brick and more particularly to bricks used in the construction of walls to form a facing or an exposed surface.

The primary object of the invention is to provide a building brick that will facilitate the layin'g thereof by eliminating the necessity of applying mortar to the ends of each brick during the construction of a wall or the like, and at the same time to ensure vertical joints that will render the wall waterproof.

A further object of the invention is to provide a building brick having cut-out portions in the ends thereof so that during the construction of a wall or the like the ends of the brick will provide central openings to receive any application of motar for joining the ends and assuring a perfect vertical joint.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawing which forms part of the application.

In the drawing: 7

Figure 1 is a perspective View of a portion of a building wall embodying the structure of the present invention.

Figure 2 is a perspective view of a building brick formed in accordance with the present invention; and

Figure 3 is a perspective view of a header or bonding brick.

At the. present time, in the construction of. building wall structure there is used a substantially rectangular brick of solid formation and it is necessary with this type of brick to apply the mortar between the layers of bricks and to the ends thereof, or sides as in the case of a header course, and the application to the ends of the bricks forms a vertical joint. It has been found that leaks in brick walls are generally due to defects in the vertical joints joining the ends or sides of the bricks. The defects are due to the present method of brick laying in which mortar is applied to the end or side of each brick, to join the bricks vertically, after which the brick is positioned on a mortar bed, previously applied for the horizontal joint, and pressed and tapped in a downward direction. In the leveling of the brick after the side or vertical joint is made, there is a liability for the removal of pressure from the vertical joint thereby causing said joint to separate. Holes or openingsare also left when either too little mortar is applied or the sidewise pressure in making the vertical joint is not sufficient to force the mortar up to the top of the vertical joint and since the usual spacing between bricks, not employing the principle of this, invention, is too small, the'mortar applied above for the next course cannot drop down and properly fuse with the mortar in such partially filled vertical joints. These holes or openings may-be partially filled in the process of striking excess mortar from the joints, but due to the factthat' the mortar at this time has already started to set and thus is too dry to adhere to the bricks and remain waterproof, such filling is very superficial and only serves to hide these defects.

With the present invention, due to the construction of the building bricks, the verticaljoints are filled from the inside thereby eliminating any chance of a defective joint.

Referring to the drawing for a more detailed description thereof, the building brick 5 illustrated in Figure 2 of the drawing, is known in the art as a stretcher brick and is preferably of I solid formation. During the melding of the brick 5 the ends are provided with recesses t and l and the inner corners are recessed as shown at 8 and 9. The recesses 6, l, 8 and'il, respectively, when aligned with an adjoining brick, form a substan' tially oval recess. Between the recessed portions 6 and ii, I and 9, respectively, there are provided shoulders Hi and I! which automatically provide for the correct spacing of the adjoining brick.

In Figure 3 of the drawing there is disclosed a header or bonding brick I2 having recessed portions [3 and M provided in the longitudinal edges thereof and as is customary, this brick is used at spaced intervals during the construction of the wall structure. The recessed portions I3 align with the recesses 6 and l, and the recesses I4 align with the corner recesses 8 and 9, as is clearly illustrated in Figure 1 of the drawing.

During the construction of a building wall structure a series of bricks will be placed on a mortar bed with the ends thereof joining to provide recesses to be filled with cement or mortar. The header brick i2 is placed at spaced intervals to provide a suitable bond and after the shoulders so and l l are joined, a layer of mortar is applied to the top surface of the bricks for the succeeding layer of bricks, and when applying the same, a portion of the mortar will be deposited in the recesses l5 formed by the joining bricks and, when filled, will be caused to press outwardly into the outer spacing l6 thereby forming a perfect vertical joint.

From the above description it will be seen that the bricks are suitably recessed at their ends or space I 6 thereby completing the vertical joint.-

The construction of a wall using the herein described brick will be expedited due to the fact that it is unnecessary to apply mortar to each end of the brick prior to its application. The mechanic thereby has free use of both hands and the bricks can be lined; against a suitable straight edge or guide and may be accurately positioned. The shoulders H automatically provide for the correct spacing of the bricks and since said bricks are not at this stage bound together at the ends, they may be easily tapped, several at a time, into place and in a straight line with the aforementioned straight edge. While applying the mortar bed for the next course, the mortar Will drop dOlWll and fill the central openings l5 and when filled press outwardly into the outer spacing l6 thereby automatically forming a perfect vertical joint. As will be seen in Figure 1 the openings 55 also form perfect lock joints thereby interlocking thebricks endwise and sidewise. and joining the mortar beds above and below the bricks.

It is to be understood that this invention is capable of extended application and is not confined to the exact showing of the drawing nor to the precise construction described, and therefore, such changes and modifications may be made therein as donot affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

This application is a substitute for the abandoned application, Serial No. 99,810, filed by the applicant on Sept. 8, 1936.

What is claimed is:

l. A bricks, certain of said bricks having a vertical groove formed in each abutting surface thereof and each having an opening, extending vertically onto the outside face of the wall, adapted to form a key-hole shaped recess in conjunction with an adjoining brick for receiving binding material simultaneously with and byapp-lication of said material to a horizontal face of said brick, whereby abutting bricks are securely aligned in a manner facilitating essentially complete filling of spaces between bricks.

2. A Wall comprising courses of bricks, prowall comprising courses of abutting jections extending from the adjacent brick surfaces, cooperating when said bricks are abutting to define recesses for receiving binding material, entraining it to the face of the wall simultaneously with application of said material to a horizontal brick surface, forming akey to assure alignment of bricks in courses and essentially complete filling of vertical spaces in the wall face.

3. A brick comprising a substantially cubiform body having a finished surface and means for spacing it from an adjoining brick comprising a first shoulder projecting forwardly. from the 5 plane of a junctional surface, a second shoulder projecting from said junctional surface in spaced parallelism with said first shoulder to define a' der projecting from said junctional surface in spaced parallelism with said first shoulder to define a recess therebetween in conjunction with an adjoining brick for receiving binding material simultaneously with the application of said material tov a horizontal brick surface of said brick forming a key for assuring alignment of adjoining bricks, said second shoulder. extending beyond said first shoulder and being adapted to cooperate with an adjoining brick for holding said first shoulder spaced from said adjoining brick, presenting a. space between the junctional surfaces of the adjoining bricks at said finish surface thereof. 7

5. A wall comprising courses of bricks arranged with certain faces in spaced adjacency; definite areas. of adjacent brick faces having vertically extending formations, substantially coextensive with said areas, horizontally flared in a locality distal relative to the front of said opening.

6. A cubiform brick having a front face and side faces cooperating to define corners of said brick; at least one of said side faces having. a substantially vertically extending projecting formation distal relative to a front corner and an internally extending cutaway area between said formation and said front corner.
